Moderators Jake Lo Posted January 26, 2017 Moderators Share Posted January 26, 2017 @mdub, your system has HD 530 whereas comi has HD520. Do either of your system have a discrete graphics card? Link to comment Share on other sites More sharing options...
comi Posted January 26, 2017 Share Posted January 26, 2017 No, mine does not have discrete graphics card. Link to comment Share on other sites More sharing options...
mdub Posted January 27, 2017 Author Share Posted January 27, 2017 No just the 530 Link to comment Share on other sites More sharing options...
mdub Posted January 31, 2017 Author Share Posted January 31, 2017 just wanted to say I got MacBookPro13,1 working with generated SSDT in 10.12.3. I added that system definition PlatformSupport.plist in /System/Library/CoreServices and it works. Battery life isn't great at around 4 hours, but CPU/GPU seem to be scaling properly. 1 Link to comment Share on other sites More sharing options...
mdub Posted February 1, 2017 Author Share Posted February 1, 2017 Looks like I spoke too soon, MacBookPro13,1 does not have correct CPU speeds for my 6820HQ. I tried using Piker's freqvectors script to change cpu vectors to MacBookPro13,3 (which matches my CPU) but this results in kernel panic (see attached pic). any idea what could cause this? HWP is not a solution for this model as graphics are not properly accelerated/power managed. on a side note I'm kinda confused why lots of people say to try different SMBIOS definitions to generate an SSDT when only 1 (MacBookPro13,3) matches my CPU and will properly implement CPU power management. Seems to me that SMBIOS is not arbitrary and that the really important thing is getting the correct frequency vectors to work. update: just saw this on Piker's blog "Update: HWP is set to 1 (enabled) in the FrequencyVectors data in the plists." if HWP is enabled in the frequencyvectors data of Mac-A5C67F76ED83108C.plist (MacBookPro13,3 plist) then how would I disable it? Having HWP + generated SSDT will cause KP so maybe this is the problem?

comi Posted February 6, 2017 Share Posted February 6, 2017 Ok, I managed to have a workaround the HDMI issue: After a cold start, log in and then sleep the laptop. Wake it up and plug the External Monitor to HDMI, now both screens work and sound work as well. Hope this help someone. Link to comment Share on other sites More sharing options...
